If you look closely at the army of Rangers in the opening credits, you can see four versions of Tommy Oliver: Green Ranger, White Ranger, Zeo Ranger Red, Black Dino Ranger. Even though he had a single clone made, he can't be four variations at the same time.

The last scene where the Rangers decide to make this their mission has the exact dialogue from the original pilot episode from 1993, right down to the pink ranger teasing she wasn't going to accept the position before saying "joking!"
